Fund Project: This work was supported by the National Natural Science Foundation of China (21434009, 51705507), Western Young Scholars "Class B" Program, and Young Elite Scientists Sponsor Ship Program by CAST (2017QNRC0181).

This paper briefly reviews four main research directions of lubrication discipline, as biomimetic hydrophilic lubrication, biomimetic lubrication drag-reduction, solid lubricant materials & technology, and liquid lubricants. We summarize the international frontiers, domestic research situation, existing problems and future development trends for each direction. The suggested research contents in future are as follows:(1) After Studying the relationship between interface hydration and lubrication along with its regulation mechanism, aim to developing biomimetic hydrophilic lubrication materials with high load bearing, low friction & anti-wear properties, and key wa-ter-lubricating coating technologies suitable for modification of high-end implanted biomedical devices, by using innovative design ideas such as layering, gradient and soft & hard composition; (2) After studying on the relationship between interface wetting and drag reduction along with its regulation mechanism, aim to developing effective gas-film stabilization technology on super-hydrophobic surfaces and elastic drag-reduction technology on super-hydrophilic surfaces to achieve efficient drag-reduction under turbulent flow condition by the bionic design of surface structures and components; (3) Applying the concept of supramolecular assembly to design new liquid lubricants and study its interaction mechanism, aim to developing new liquid lubricants with anti-irradiation, anti-aging, anti-climbing, anti-corrosion, environ-ment friendly and reusable characteristics, by precisely designing molecular structures and controlling the preparation technique; (4) Developing solid lubrication materials with excellent friction-reduction, anti-wear, long serving-lifetime, radiation resistance, corrosion resistance, strain resistance and wide temperature-range adaptation characteristics, by adopting novel concepts of surface and interface physichemistry, such as layered, soft/hard composition, multi-component coupling, gradient and in situ healing.
